Public bug reported:

Steps to reproduce:
1. login using Unity
2. press [Super/Windows] + [P]

What is expected to happen:
I don't know?! I'd expected nothing to happen, since this isn't listed in the 
shortcut overview, opened by holding [Super]

What actually happens:
The X-Server crashes with a "broken pipe"-error

Stacktrace:
Program received signal SIGPIPE, Broken pipe.
